LASTNAME + FIRSTNAME

I'm trying to be able to edit the computed column (NICKNAME) = LASTNAME FIRSTNAME and change to...

What about adding a new derived column and index to each table that creates a hash across the 30 fields. Then do a compare of the hashes.

ALTER TABLE <tablename>

FROM MyTableName AS...

You can always import it in batches

1 - Insert a new column before "A". Add a UniqueKey to this column. It could be as simple as an incrementing...

TotalEntered = SUM(Entered) OVER (PARTITION BY USERNAME),

Now let's compare your query when the optimizer uses a clustered index to when a UNIQUE nonclustered index is available (if you run this with "include actual execution plan"...

I have just walked into a #$@%storm that needs my full attention. I will take a closer look at your suggestions as soon as I can.
